Abstract:
This research project presents the design and development of an Interactive Pressure Control Trainer with Actuator and Sensor-Based Interface, intended to address the lack of practical training tools in engineering education, particularly in under-resourced institutions like Tagoloan Community College. The primary objective of the study was to create a low-cost, functional, and modular training system that simulates real-world pneumatic pressure control scenarios for hands-on learning. The system integrates a programmable logic controller (PLC), pneumatic actuators, pressure sensors, solenoid valves, and a human-machine interface (HMI). It operates in both manual and automatic modes, with wireless control supported by an ESP8266 microcontroller and a Bluetooth-based Android application. The prototype allows users to monitor and control pressure levels in real time, providing a practical and interactive learning experience. Methodologically, the project followed a systematic process including system design, component selection, software programming, physical assembly, and performance testing. The evaluation was conducted using the ISO 9126 model, focusing on five quality attributes: functionality, reliability, efficiency, maintainability, and portability. Feedback was collected from 30 participants, including engineering students and faculty members, using a structured Likert-scale survey. Key findings show that the prototype effectively meets educational goals, with high scores in functionality (mean = 3.88), efficiency (mean = 3.81), and portability (mean = 3.90). Students found the system intuitive and engaging, while educators recognized its potential to enhance technical instruction. Minor issues related to Bluetooth communication and pressure sensor calibration were addressed during testing. In conclusion, the developed trainer successfully bridges the gap between theoretical concepts and real-world engineering practices. It provides a scalable solution for hands-on technical education and demonstrates how innovation can overcome resource limitations in academic settings. The system holds strong potential for adoption in other engineering programs seeking affordable automation training tools.
